In the 1989 flick Back To The Future: Part II, Marty McFly travels to the far-off year of 2015 and gets roped up in a thrilling Hoverboard chase with a gang of bionic hooligans. But before director Robert Zemeckis could film the scene, the crew practiced their hoverboard stunts in fields and studio lots. Watch as an ersatz Marty flies with the greatest of ease.
